Answer:
The black curve is the graph for given function.
Step-by-step explanation:
We are given the following function in the question:
We have to graph this function.
Properties of function:
- The given function is an exponential function of the form
, where b is the base and x can be any real number.
- Here,
- It passes through the point (0,1).
- Since
, the graph of function will will increase as we move from left to right.
- The domain for given function is all real numbers.
- The range for the given function is
The attached image shows the graph for the given function.
$4 is the original price of the jar consisting of peanut butter so therefor it = 100%. It's for sale at $3.60, so we divide $4 by 100% so we get the percentage for each cent and then we times it by 3.60 to get the percentage for $3.60 which is 90%. Now we subtract 90% from 100% to get the discounted percentage for 40cents :)
